  1. 16" 5.56 chrome lined barrel 5 Star Review

    Great Product, awesome value

  2. excellent value 5 Star Review

    Posted by on 10th Apr 2018

    Best group to date with this barrel 1.375" at 100 yards with fed xm855. ( free floated, standard mil trigger, standard a2 muzzle, 4x optic. ) I consider this very good performance for a pretty standard setup.

    I am confident that this barrel is capable of grouping well under an inch at 100yrds with a better ammunition selection/trigger upgrade.

  4. Green Mountain Does it Again! 5 Star Review

    Posted by on 7th Nov 2016

    Service, delivery and value is what keeps me coming back to Green Mountain.

    I just completed a billet Ar-15 build and spared no expense on what components I wanted. When it came down to one of the most important features the barrel, I knew there was only one choice Green Mountain.

    Rifle shoots straight / true through to the fit / finish which is top notch. The letter showcasing their pride towards servicing their customers, shows a certain level of class.

  5. Range Report 5 Star Review

    Posted by on 1st May 2016

    This is the second barrel I've bought from here. Fit and finish was outstanding as usual. Install was simple and interfaced perfectly with an Aero Precision upper and a YHM Diamond FF.

    The accuracy of this barrel was mind blowing for the price. Grouping was done at 25m. M855 produced groups that were tight enough that you could just barely see the individual holes. I then ran some Berger 55gr hand loads. Those repeatably produced groups that looked like single ragged holes.
